Heat Flow Can Now Be Controlled Through Switch


Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows ‘on’ or ‘off’. Heat flow occurs whenever you have a region of higher temperature near a region of lower temperature. In order to control the heat flow, we engineered a specific heat flow path between the hot region and cold region, and then created a way to break the heat flow path when desired.
